Adding 9.4.0 dll's to my project

I was using Tweetinvi 9.3.3 via Nuget and all was working wonderfully. However I need to use ExtendedEntities, so i need 9.4.x. I see Nuget is not updated to 9.4.x yet, so I downloaded the dll's, removed Tweetinvi 9.3.3 via buget, then added the references
to the 9 Tweetinvi dlls.

My project now wont build, because of the using statements. It cannot find Tweetinvi.x (x = anything), saying "the type of namespace name 'x' does not exist in the namespace 'Tweetinvi'"

If I type, for example, 'Tweetinvi.C' it will prompt me with 'Tweetinvi.Core', so it knows it exists, until it builds...
